Everything connected to the Internet requires an IP address, a dotted quad number that looks something like this: 192.168.100.100. This is the current Internet Protocol (IP) known as IPv4.

Aside: given the vast number of new devices accessing the Internet, IPv4 is quickly running out of unique addresses and is likely to be replaced by IPv6 but that’s a topic for another post.

When working with Internet Protocols it is sometimes handy to verify what your IP address is (e.g. proxy detection, connecting to a remote desktop, or troubleshooting with tech support). This is where this month’s Cool Tool comes in.

What Is My IP Address not only reports back your actual IP address number but all the info associated with it such as city, state, country, and company name. Ever wonder how some websites “know” your location? This is how.
